A Japan-bound flight turned into a terrifying ordeal Monday evening after a sudden drop in cabin pressure forced an emergency landing, leaving passengers shaken and in tears.
Spring Airlines Japan flight IJ004, en route from Shanghai’s Pudong Airport to Tokyo Narita, was diverted to Kansai Airport in Osaka following the mid-air scare. The Boeing 737-800, carrying 191 people, rapidly descended over 10,000 meters in just 20 minutes after pilots detected a cabin pressure abnormality.
“I thought I was going to die,” one passenger wrote online, recalling how oxygen masks dropped from the ceiling and the cabin descended into a heavy silence. “My legs are still shaking.”
Passengers described scenes of panic and helplessness. One woman told The Standard that she saw flight attendants near tears, which only deepened the fear. Another reportedly wrote a final message to her husband as the plane plunged.
Japan’s transport ministry confirmed the flight crew declared an emergency and coordinated with air traffic controllers to land safely at 8:50 PM local time. No injuries were reported.
However, the ordeal didn’t end on the tarmac. Passengers were left inside the aircraft for over an hour without proper updates. Complaints surged, prompting Spring Airlines Japan to offer 15,000 yen in compensation per passenger—but only through a claims process.
The incident renews scrutiny of the Boeing 737-800, a model with a troubled safety history including the 2022 China Eastern crash and the 2024 Jeju disaster. Though Monday’s emergency had no fatalities, the psychological impact was lasting.
“We’re alive. That’s all that matters…But I’ll never forget the feeling of that fall,” said one survivor.
Spring Airlines’ parent company in China clarified that the affected flight was operated by its Japanese joint venture with Japan Airlines. JAL, which assumed majority control of Spring Airlines Japan in 2021, has yet to issue a public statement beyond confirming the safe landing.
